文摘We propose a new multipath mitigation technique based on cross-correlation function for the new cosine phased binary off-set carrier （cosine-BOC） modulated signals, which will most likely be employed in both European Galileo system and Chinese Compass system. This technique is implemented to create an optimum cross-correlation function via designing the modulated symbols of the local signal.
